ROLL AND FASTENING MEANS THEREFOR.

Specification of Letters Patent. Patented M 9, 1920 Application filedNovember 7, 1917. Serial No. 200,692.

To all whom it may concern Beit known that we, GEORGE J. FALLESEN andWALTER L. FARLEY, citizens of the United States of America, residing atRochester, in the county. of Monroe and State of New York, have inventedcertain new and.

useful Improvements in Rolls and Fastening Means Therefor, of which thefollowing-is a full, clear, and exact specification.

This invention relates to means for fastening rolls of sheet material toprevent unwinding. More particularly it relates to improvements inadhesive bearing fastening strips, such, for example, as are used onphotographic roll-film cartridges and are known in the art as pasters-orsticker-bands.

One object of this invention is to keep the fastening strip inconvenient position and proper condition'until used. Another ob-- jectis to prevent prematureadhesion of the fastening strip. Still anotherobject is to provide a fastening strip that will not crack when normallyfolded. A-further object is to provide a strip which may be used,to-fasten rolls of paper which are resistant to adhesive.- Yet anotherobject is to conveniently locate such a fastening strip in aphotographic cartridge and on that end of the film supportingleadingstrip or backingin a'measure, reinforce'the end of the leadstrip, which will be on the outside of the roll when the latter isremoved from a. camera after exposure. -A still further ob]ect is to solocate the fastening strip near the end of the lead strip of aphotographic film element that it will be conveniently accessible yetWlll not interfere with the insertion of the lead strip in the slot of awinding spool but w1ll,

strip. Other objects will hereinafter apar. Since this invention isparticularly satisfactory when used in photographic film cartridges, weshall describe its embodiment in such a cartridge by way ofillustration. It will be, of course, understood that the invention i'snot confined to this particular example but is capable of other formswithinthe scope of the claims. a

In the accompanying drawing Figure is aside elevation of a film cartrigo in which our invention is embodied, the roll being fastened. f Fig. 2is a cross section taken upon the line 2-2 of Fig.

, which will be hereinafter referred to.

Fig. 3 is a transverse cross section on a larger scale than Fig. 2 andshowing the] of the backing paper partly unrolled to show the foldedend'of the fastening strip.

Fig. 5'is a perspective view showing the parts in an intermediate stageof manipulation with the free end of the fastening strip in extendedposition. Fig. 6 is a central transverse section showmg the parts in thesame relative position as Fig. 5. Fig. 7 is a detailed view of thefastening strip.

Fig. 8 is a detailed view of a modification.

Figs. 9, 1 0 and 11 are sectional views of the film strip with itsaccompanying papers in.

unrolled condition, these several figures illustrating different wellknown arrangements.

The film spool shown in the accompanying drawing is of the conventionaltype comprlsing a hub 1 and the end flanges 2. To this hub there isfastened the inner end of a stri or sheet 3 of paper of suitable opacityanii having special adhesive resisting features It is wound uponthe-spool in a series of convol'utions, as indicated in Figs. 2, 3, and6. Intermediate the ends of this strip there-is attached in any of theknown or preferred ways a'band ofphotogr'aphically sensitive film of theconventional type; thus the film 10 may be backed by the paperthroughout its len h, as shown in Figs. 9 and 10 or the ends 0 the filml0 may be joined to sections 3', 3 of the paper strip.- Also, carbonpaper 12 or other strips may be operatively associated with the film asshown in Fig. 9. All of these structures are well known in the art.

The usual stickers 13 and 14 for attaching the film to the backing sheetare shown. p

' The roll is fastened in its coiled position by a strip designatedgenerally by S. This strip is attached. in the preferred form at 6 tothe outer end of the sheet 3., On the inner face of the free portioifthere is located an adhesive area or portion 9 which, when the end 7 isbent at.8 over-the end of sheet 3, willv be brought into contact withthearea on the inner face of said sheet, as indicated in Figs. 3 and 4.The parts being wound, up after I being in the position shown in Figs. 3and 4, the adhesive portion of the strip S will be stored between theouter convolutions of the sheet or backing strip 3. As most clearlyindicated in Fig. 4, the end of the sheet 3 is shaped at 4 so as toconveniently enter the slot of a winding spool and, since the parts 6and 7 of the stri S are folded to lie against the faces of the sl feetthey will not interfere with the introduction of the end of sheet 3 intothe slot, but will rather act to reinforce such end and help it towithstand the initial winding stresses.

The strip S is preferably and normally located upon that end of the.sheet or backing strip 3 which is on the outside of the roll after .thefilm has been exposed in the g 4. If the film, however, be used in acamera in which the sheet or strip 3 and its film parts are drawn ontothe winding roller and then rewound back upon the supply spool, as incertain types of panoramic cameras,

' then the strip Swill be both initially and finally located upon theouter end of the strip 3, as shownin Figs. 3 and 4. It will i bethreaded into the slot of the winding roller together with the end ofstrip 3 during the loading of the camera and will be removed from suchslot at the end of the rewinding operation.

Thus, in any event, the cartridge will have the strip -S accessible formanipulation when it is removed from the camera. To fasten the roll, thefree end 7 of strip S is turned outwardly from the position shown inFigs. 3 and 4 to the osltion shown in Figs. 5 and 6, straightening outthe folded portion 8 and conveniently locating the adhesive portion orarea 9 for moistening or other preparatory treatment. After suchtreatment, the strip is wound around the roll and the adhesive portion!)stuck down. Preferably the strip- S is of greater length than theoutermost convolution of the roll so that its ends will overlap and thearea 9 will adhere to the portion 6, the roll being encircled and heldby the latter, as indicated in Figs. 1 and 2.

Inthis preferred form of our invention the strip S bears the adhesivearea or portion 9 at its outer end so that the portion 8, which isfolded, will be normally free from the usually brittle adhesive andhence the danger of cracking or weakening the stri S at the portion 8will be avoided. Wit some forms of adhesive this precaution may not benecessary and we have therefore illusnaaaaoo trated in Fig. 8 amodification in which the whole inner face of the free end of strip S iscoated with suitable adhesive 11.

The adhesive 9, prior to use in the camera, is stored in the cartridgebetween convolutions of sheet 3, as stated above. -Unless some provisionbe made toavoid it, the adhesive may become prematurely fastened to theinner face of sheet 3, especially in hot or humid climates. When theoperator attempts to fasten his roll, such a premature adhesion willprevent the hereinabove described attaching operation. It is an imortant part of our invention that were uce the possibility of thistrouble to a minimum. To that end, we make the area of sheet 3 Whichcovers the adhesive 9 and against which it is's'tored, resistant to theadhesive, even when the latter is moist. By resistant we mean that the.adhesive when manipulated in the normally intended way by the operatorwill not reliably stick or adhere to the surface or area. This adhesiveresisting area against which the adhesive ortion 9 is stored is mosteasily obtained w en the entire sheet 3 is composed of resistantmaterial. For example, if sheet 3 be made of socalled waterproof paper,itv will be resistant to adhesive portion 9 when the latter is composedof the ordinary adhesives .customarily used on the pasters or stickerbands employed at present in the art.

ile we prefer to use an entire sheet of material that-isadhesive-resistant on both sides, our invention is, of course, notlimited to such a form and the paper may be of the kind in which theinner surface only, or

even a portion of such inner surface, is made adhesive resistant, theimportant point hein that adhesive portion 9, rests against a suitablyresistant area.

While the adhesive portion 9 is normally dry until ready for use, it isnot necessarily so, but may be more or less tacky or moist .Withoutharm. While we refer to attach the strip S to the outer si e of the endof sheet 3, we do not wish to be limited to such attachment except asspecified in the accompanying' claims, our invention comprising in itsbroader aspect the employment of a strip even where the portion 6thereof is not initially fastened to the sheet 3. Where the portion 6 ofstrip S is attached to sheet 3,

any preferred mode may be employed; .A special adhesive toward whichsheet 3 is not resistant may be used or the adhesive used in attachingportion 6 to sheet 3 may be the same adhesive that is employed inportion 9 and toward which said sheet is normally resistant, theadhesive on portion 6 being given an abnormal or special treatment tomake it adhere to the strip. It is furthermore noted that the attachmentof portion 6 to the end of sheet 3 is chiefly a convenience duringstorage and it is not subject to as great stresses as those which pullon the strip when-the latter is used to fasten the roll. Consequently aunion or adhesion which would be unreliable and impracticable whenfastening the roll will be entirely satisfactoryfor holding-portion 6tosheet 3 during storage. In the preferred embodiment of our inventionwe make use of this fact and the adhesive area 10, which holds portion 6to sheet 3, is of the same substance as the adhesive in area 9.

While in the preferred form of our invention strip S is of sufficientlength to encircle the roll and be fastened by an overlapping adhesivejoint, it will be understood that within the scope of our invention, thestrip S maybe of shorter length and the adhesive 9 may be stuck to oneof the outer convolutions of the sheet 3 wherever the outer face ofsheet 3 is less adhesive-resisting than the inner face thereof.
